by who(m)-passive

[aysaa]

Hi,

Question 1:

A : He was murdered
B : By who? / By whom? / Who by? / Whom by?

Question 2:

By whom was America discovered?
Who was America discovered by?

In the first example, I chose 'by who' or 'by whom'.
In the second example, I prefer the second.

Could you please tell me your opinion?

Thanks.

Question 2:

Thanks.

In question 2 "By whom was America discovered?" is correct. More natural would be "Who discovered America?"

I have always seen this expanation from the teachers on net such as (by) who / whom ...? [question using passive voice] - WordReference Forums

By whom was the book written? (extremely formal)
and
Who was the book written by? (everyday speech and writing).


Thanks.

Who was the book written by? (everyday speech and writing).

But even more natural: Who wrote this book?
